Front-End Amplifiers for Tuning Forks in Quartz Enhanced PhotoAcoustic Spectroscopy

A study of the front-end electronics for quartz tuning forks (QTFs) employed as optoacoustic transducers in quartz-enhanced photoacoustic spectroscopy (QEPAS) sensing is reported. Voltage amplifier-based electronics is proposed as an alternative to the transimpedance amplifier commonly employed in Q...
